HYDRAULIC DIVERSION VALVE

The versatile DN125/5 CF Hydraulic Diversion Valve can be set-up to operate in two different modes. As a switcher valve, it can be used in set-ups where one concrete pump is feeding two placement lines. Using this technique, a smooth and quick conversion can be made from one line to the other to increase the concrete placing capacity and flexibility of the entire system. As a Shut-Off Valve, the hydraulically powered switcher valve is installed in the horizontal placing line at the base of the vertical rise to shut off the line. The line from the pump is connected to one of two inlet ports. The other inlet is then fitted with a cap or piped to a designated area for concrete disposal. The outlet port is connected to the placing line system. The concrete filled line can then be hydraulically switched to the side with the cap, thereby holding the vertical head of concrete while the pump is stopped. Valves that use 5″ HD ends have a maximum pressure rating of 3,000PSI.

HYDRAULIC DOUBLE DIVERSION VALVE 

The versatile DN125/5 CF Hydraulic Double Diversion Valve works as a push pull operation. The push pull is done by two 4” bore 12” stroke hydraulic cylinders. A manually operated hydraulic directional control valve is mounted on the unit. Two replaceable, hardened steel rings provide a seal between the 1-1/2” thick valve plates. Pressure of hydraulic control system cannot exceed 2500psi (172bar). The diversion valve body is rated at a nominal concrete working pressure of 3190psi (220bar) when new. The valve can be operated as a double diversion valve; one inlet, two outlets with a clean out port for each outlet, or a double diversion valve; with one inlet, a priming port and two clean out ports, a stop plug may be installed into the shorter pipe on the double flange assembly to deadhead the line in one position.

MANUAL

MANUAL DIVERSION DISCHARGE VALVE

Used on horizontal runs when changing flow of concrete is required, as in large wall and mat pours. Valves not to be used where high head pressures are involved. The V50DD02D has an operating pressure of 130bar / 1885 psi. Consult factory for operating pressures for other valve sizes. > VIEW OPTIONS

MANUAL DOUBLE DIVERSION DISCHARGE VALVE

Used on horizontal runs when changing flow of concrete is required, as in large wall and mat pours. Valves not to be used where high head pressures are involved. The V50DBD05D has an operating pressure of 28bar / 400 psi. Consult factory for operating pressures for other valve sizes.

MANUAL WYE DIVERSION VALVE

Diversion WYE valves are used for going back and forth from one horizontal pumping line to another.  > VIEW OPTIONS

MANUAL COLUMN SHUTOFF VALVE

The column shut-off valve is designed for use on forms having flat or curved surfaces. Round forms of usually small diameters may require modified base plates. The standard base plates provide multiple mounting holes, as shown in picture. Typical spacing is 8-10 feet maximum between valves. Forms must have sufficient opening at the top to prevent uplift of forms. Maximum rated working pressure of V50CSD is 200psi (14 bar). Consult factory for details and ratings of other sizes. > VIEW OPTIONS

MANUAL HOSE SHUTOFF VALVE

The hose shut-off valve features a welded valve body assembly with 3/8″ steel sliding plate. This valve provides a lower cost alternative to the hammer shut-off valve. This style can not be disassembled for cleaning, and has generous clearances built in. Maximum pressure rating is 200 feet vertical. > VIEW OPTIONS

MANUAL HAMMER SHUTOFF VALVE

The hammer shut-off valve features versions with single or dual hardened seal rings. A heavy plate is used to construct the sliding plate and side plate. The removable side plates facilitate cleaning. Maximum pressure rating is 300 feet vertical.  > VIEW OPTIONS

MANUAL HEAVY HAMMER SHUTOFF VALVE

The heavy hammer shut-off valve features dual hardened seal rings. A heavy plate is used to construct the sliding plate and side plate. The removable side plates facilitate cleaning. Maximum pressure rating is 1885 psi. 

PNEUMATIC

AIR CUFF SHUTOFF

Safely stop the flow of concrete remotely & reduce the chance of hose whip. Air Cuff Hose Shut Off Valve manages spills and stops flow by collapsing the end hose from the outside using an inflatable bladder. This action also helps stop air from getting trapped inside the pipeline, which reduces the chance for hose whip. Controlled by either remote control or integration with the pump’s control circuit. For use on all boom trucks and placing booms. > LEARN MORE

INLINE UNDER WATER AIR SHUT-OFF VALVES

Underwater valves are designed to prevent water from mixing with concrete in under water concrete placing operations. Valves are simple in design, eliminating sliding, rotating, swinging and plunging parts and can be used in vertical and horizontal positions. Valves operate with low pressure, sealing around solid objects, and closing against back-flow. The valve body is reinforced with steel plies for durable use. Valve opens when air pressure is released, or when concrete pressure exceeds the holding air pressure. 

INLINE AIR SHUT-OFF VALVES

Inline valves are designed to work inline with boom systems. Valves are simple in design, eliminating sliding, rotating, swinging and plunging parts and can be used in vertical and horizontal positions. Valves operate with low pressure, sealing around solid objects, and closing against back-flow. The valve body is reinforced with steel plies for durable use. Valve opens when air pressure is released, or when concrete pressure exceeds the holding air pressure.

TWIN CYLINDER BOOM TIP SHUT-OFF VALVE

The Twin Cylinder Boom Tip Shut-Off Valve can drastically reduce the chance for hose whip. A very dangerous situation in concrete pumping. By stopping the flow of concrete at the boom tip, air simply doesn’t build up between the sections like it can without the valve. Hose whip is the leading cause of serious injury on the job site while pumping concrete. When you eliminate that risk you have a much safer pour.

  • Shuts off concrete flow automatically when the pump is stopped, allowing the operator to focus on running the pump

  • Minimizes plugging caused by free falling concrete in the line while minimizing the amount of air trapped in the boom system, both are a major cause of hose whipping when restarting the pump

  • Valve is compact enough to fold up the boom without removing the unit

  • Will not damage boom hose, mounts after last tip elbow

  • Rebuildable
